Abstract
The utility model relates to a lighting charging flashlight. The utility model is characterized in that an ordinary zinc-manganese dioxide dry cell which is considered to be unable to be charged can be charged time and again; thereby, the expenses can be economized, and the environment can be protected. The charging circuit of the ordinary zinc manganese dioxide dry cell is positioned in the casing of a flashlight. By using few electronic elements, the charging circuit can have the functions that the voltage reduction is realized, the rectification and the display are realized, the charging current can be automatically controlled, and the over charge can be protected; thus, the utility model has the advantages of simple structure, small volume, low cost, easy fabrication, easy installation and easy use.
Description
The utility model relates to a kind of illuminating chargeable flashlight, particularly can give the flashlight of common zinc-manganese dry battery charge.
Present existing chargeable flashlight, its charging circuit can not be given common manganese dry cell charging, the dry cell that is adopted is more expensive chargeable No. 5 dry cells of price, the cost height, capacity is little, and its inside welds together battery and charging circuit, can't change battery, in case battery damages, whole torch just can not use.Be difficult to apply.
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, and providing a kind of can with energy savings, reduce environmental pollution effectively to the flashlight of common zinc-manganese dry battery charge, and it is more convenient that people are used, and spending is more saved.
The technical solution of the utility model is: common zinc-manganese dry battery charge circuit (10) is placed in the flashlight housing (1).
Torch housing mid portion is a battery compartment (4) of laying battery, its head is equipped with lighting bulb (2), switch (3) is equipped with in a side at housing, charging circuit plate (10) is installed in the afterbody in the housing, be provided with one in housing afterbody side and settle the indicator hole (14) of sending out diode, input supply socket (5) is installed in the housing afterbody, other has alternating current input power supplying line (6), when need charge, the end that this power line has a stealthy plug (16) inserts in the socket (5) on the torch housing tail end, and the other end inserts the 220V AC Power supply socket.
The utility model is simple in structure, uses few electronic component, can realize step-down, rectification, demonstration, control charging current and over-charge protective function automatically, and volume is little, and cost is low, does not have switch in the charging circuit, is convenient to make, installs and uses, and very easily promotes.
Description of drawings:
Accompanying drawing 1 is an embodiment common zinc-manganese dry battery charge flashlight cross-sectional view.
Accompanying drawing 2 is an embodiment common zinc-manganese dry battery charge line map.
Below in conjunction with accompanying drawing, further specify the utility model by embodiment.
The utility model places flashlight housing afterbody with common zinc-manganese dry battery charge wiring board (10), and the power input (11) on (10) is linked to each other with power input socket (5) on the housing tail end by lead.By the stealthy plug (16) and AC power connection of alternating current input power supplying line (6), finish after pull up (6) again by charging for this socket (5) when charging, and it is promptly convenient again safely to use.
When using this flashlight lighting, open flashlight housing lid earlier,, again case lid is built the battery battery compartment of packing into, Closing Switch (3), small electric bulb is promptly bright, and cut-off switch (3) gets final product when stopping using.
During to battery charge, input plug one end of alternating current input power supplying line (6) is inserted the 220V AC Power supply socket, another is exported stealthy plug (16) and inserts in the AC in connector (5), at this moment, the power input (11) of wiring board (10) promptly and power connection, the positive and negative polarities of battery are connected by elastic sheet metal (7), spring (8) and charging lead (15) and the dc output end (12) on the wiring board (10), a diode that is contained in the torch housing tail end side indicator hole (14) is shinny, and then the explanation charging is normally carried out.When stopping to charge, only need the two ends plug of alternating current input power supplying line (6) extracted from the AC in connector (5) of torch housing tail end and alternating current 220V supply socket respectively and get final product.
Form the step-down link by capacitor C, bleeder resistance R for the circuit of common zinc-manganese dry battery charge, the rectification link that V2, V3 two rectifying tubes are formed, the charging that V2, V3, V4 form shows link, the over-charge protective link that V1, V2, V3, V4 form.The positive pole that is recharged battery is connected with the A end of capacitor C, and the negative pole of battery is connected with the anodal B end of commutation diode V2, and AC power is from the negative pole N end input of the M end and the commutation diode V3 of capacitor C.
The charging principle of this circuit is, is in the positive half period of bearing at AC power M end for positive N end, electric current to capacitor C charging, is equivalent to through electric capacity by the M point, be recharged the loop that battery and commutation diode V2, V3 form gets back to the N end, finishes the half-wave charging process to battery.At M is negative, N end is in the positive negative half-cycle, and electric current realized capacitance discharges and reverse charging through the loop that voltage-stabiliser tube V1 and capacitor C form by the N end, created condition in second cycle battery being continued to charge, so move in circles, promptly realized charging process battery.
When battery just begins to charge, cell voltage is lower, voltage-stabiliser tube V1 can conducting at positive half cycle, electric current in the circuit all charges into battery, along with constantly increasing of cell voltage in the charging process, when the voltage sum of battery total voltage and luminous tube V4 reached the voltage stabilizing value of voltage-stabiliser tube V1, voltage-stabiliser tube V1 began in positive half cycle conducting.Because this circuit is a constant-current circuit; so conducting along with voltage-stabiliser tube V1; the electric current that charges into battery will reduce gradually; the voltage of battery is high more; the electric current that flows among the regulation pipe V1 is just big more; until almost all electric currents all from voltage-stabiliser tube V1, pass through, thereby battery has been played effective over-charge protective effect, unlikely filled bad.Simultaneously, along with charging into reducing of electric current in the battery, light emitting diode V4 is deepening gradually also, shows that battery is sufficient.
